Integrated Flange for Axial Location
The outer-ring flange seats against the rack housing shoulder, fixing the bearing axially without separate retaining hardware. In EPS racks, this eliminates a common source of end-play and misalignment during rebuilds.
Four-Point Contact Geometry in a Compact Envelope
The raceway accepts combined radial and bidirectional thrust loads within a single bearing width. For steering rack support positions, this geometry delivers the stiffness of a paired angular contact arrangement without the axial stack height.
Solid One-Piece Inner Ring
Unlike split or two-piece inner rings, the one-piece construction resists deformation under the bidirectional thrust reversals typical of steering inputs. The result is maintained preload and geometry over service life, not just at installation.
ZZ Double Metal Shields
Low-friction metallic shields keep coarse debris out of the raceway while supporting the rotational speeds seen in EPS motor-driven racks. The shielded, pre-lubricated configuration is intended for maintenance-free service life inside the steering assembly.
